Description

Classic quality

804 D4 is perhaps more conventional in appearance than other floorstanders in the 800 Series Diamond range, but it’s every bit as sophisticated. Its new Reverse-Wrap cabinet is both a mechanical and acoustic revolution in its class, and its new plinth ensures rock-solid, accurate bass response too.

Aluminium top-plate

Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminium top-plate. This also provides a perfect mounting point for all-new Leather by Connolly trim, with luxurious black leather for dark cabinets and light grey for lighter finishes.

Reverse Wrap cabinet

Instead of a conventional loudspeaker box, the cabinet in 804 D4 is made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.

Aluminium plinth

A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminium plinth complete with a steel constrained layer damping sheet, which controls unwanted resonance. It also has greatly upgraded spikes for maximum stability and durability.

The science of sound

Innovation is at the heart of everything we do. We question, we examine, we understand and then we evolve. We use computer modelling to explore and reimagine every aspect of loudspeaker design. Learn more about all the technologies that combine to make 800 Series Diamond so special here.
